I'm Keima Masuda, a Dungeon Master aiming for a life without work. Haku told me about there being a Hell Tournament in the Demon Realm with the reward being the Divine Pajamas, and she even sent me over as an imperial official. She's being so generous I can't help but feel like something's off... And of course, the winner of this year's Hell Tournament suddenly forces me into a fight. "Now then, in accordance to the law, you are now mine." What?! If you lose a duel in the Demon Realm you'r...

What do the US Marines, freight rail staff, computer programmers, Formula 1 drivers, and health care practitioners have in common? They all experience errors and failures at work and the same set of models can explain why and how they can improve failure reduction. Failure learning has emerged as a vibrant interdisciplinary area of research. This book brings 14 scholars together in an edited volume containing failure studies and highlighting learning issues in settings such as freight rail...

I'm Keima Masuda, a Dungeon Master aiming for a life without work. I finally got back home from the imperial capital, only to find a whole new town on the other side of the mountain! Apparently they're copying our town and they have their own inn. In other words, less customers and work for me! Heck yeah! Or so I thought, but... Why am I getting more customers? There's even someone with a suspicious-sounding "Artifical Dungeon"..."You always see right through me, Keima... Perhaps t...

I'm Keima Masuda the Dungeon Master, still chasing my dream to live a life without work. I finally get home from my trip to the Demon Realm (where I spent basically the whole time as a slave), but now Aidy the Demon Realm's princess is visiting the empire. I knew I'd be forced to give her a tour, but..."Can you do nothing about how dreadfully boring it is here, town chief?"The peaceful empire is simply too boring for Aidy! I have to go hunt down someone for Aidy the battle ...

I’m Keima Masuda, the Dungeon Master, still chasing my dream to live a life without work. Aidy finally returned to the Demon Realm, but sadly, peace only lasted for so long.“Papa! Mama! Hi, I’m your daughter!”Out of nowhere, Rokuko and I had our first child?! Why?! Isn’t Haku going to kill me now?!I narrowly avoided death by being frank as possible, but in return got stuck solving some problems in Daide. That would have been fine, but Leona had traps waiting for us?...

I'm Keima Masuda, a Dungeon Master who dreams of a life without work. I finally arrive at the imperial capital, only to find Haku asking me to serve as a producer for some rabbit-type Dungeon Core's dungeon! While working out plots and trying to think of some ace up my sleeve, suddenly she returned. ""You're going to crush Core 564, yes? I shall help you."" For some reason, Rokuko's true friend (arch enemy) Aidy joins the fray! Thus begins a chaotic Dungeon Battle of fluffiness, idols, and...

I’m Keima Masuda, a Dungeon Master slash Town Chief slash Pope that dreams of a life without work. With the dragon (my neighbor's daughter) that was causing trouble in town defeated, I was summoned to the imperial capital to be awarded for my efforts. Or rather, so Haku could see Rokuko, but whatever. As long as I get a day off work!“I am Emmymephy, first princess and heiress apparent of the Laverio Empire!”Yep, more crap to deal with! I’m traveling to the capital with Wata...

I’m Keima Masuda, the Dungeon Master, still chasing my dream to live a life without work. Just as we settled that Leona business, Haku piled more work onto us... She wants us to destroy some artificial dungeon plant in the Holy Kingdom, but I just got back from Daide and want to chill at home! What to do, then?“I may have an idea that will neatly solve all of these problems. May I speak?”At Toi's suggestion, who Haku had forced onto me, I decided to go to the Holy Kingdom b...

Even dragons fall in love?!My name’s Keima Masuda, and despite the fact I’m aiming for an easygoing life I’m a Dungeon Master, a town chief, and a pope. Goren Town’s busy with a Beddhist wedding ceremony, and now a dragon’s attacking? I feel like this is gonna be one crazy foe...“My bad, Keima! Seems like my dumb daughter’s giving you trouble!”It was my neighbor (dungeon)’s daughter, Igni (300 years old). That’s fine, but now there’s a bunch of adventurers coming to...

I’m Keima Masuda, a Dungeon Master aiming to not do any work. Several months after bringing the Holy Kingdom under my control, Haku managed to land the finishing blow on Core 10, who previously got away. I thought I was finally about to get all the pieces of the Divine Bedding and be as lazy as I want now that he’s gone, but...“Sorry, Master... Laters.”Ichika’s betrayal leads to our dungeon being attacked! Haku appears to be behind it, but there’s something off about her......

I’m Keima Masuda, a Dungeon Master aiming to do nothing all day! That’s the idea anyway, but for some reason I’m the town chief, the pope, and I’ve got a noble daughter under my care. To make matters worse, a pair of beastkin siblings Ichika used to adventure with came to town. Seems like the older brother’s in love with Ichika... and he wants to fight me for her? He’s misunderstanding something, but I won’t let anyone get in the way of my sleep! Time to beat the crap out of him and go bac...

In my attempts to keep my dungeon running without doing any work myself, I ended up becoming a pope on top of being town chief. That must have made me stand out a little too much, because the Tsia Archduke has a quest he wants me personally to do. I was thinking I'd meet him and turn him down, but the reward is information about the Divine Pillow?! Okay, I guess I'll accept it."Very well," says the Archduke. "I will accept your marriage with my daughter, Maiodore."Wait a se...
